Adequacy Assessment Considerations in Wind Integrated Power Systems

There is a wide range of possible data representations, models and solution techniques available when conducting adequacy assessments of wind integrated generation or composite generation and transmission systems. This paper presents some of the basic factors and procedures that need to be considered when conducting wind integrated system adequacy assessment. Focus is placed on possible wind speed data models, wind energy conversion system models and their application in generation and bulk system adequacy evaluation. A series of studies is presented using two published test systems, the RBTS and the IEEE-RTS. These studies illustrate the effects of wind farm correlation on the determination of wind power capacity credit indices and on general adequacy assessment in generating and bulk electric systems. The impacts on the system wellbeing indices of adding wind power to a bulk electric system and the effects on the adequacy of a wind integrated system from energy storage obtained using hydro generation are examined by application to the IEEE-RTS.
